SPECIFICATION forming part of Letters Patent No. 255,632, dated March 28, 1882.

Application filed August 15, 1881. (No model.)

To. all whom it may concern:

Be it known that I, GUSTAV L. JAEGER, a citizen of the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Machines for Cutting and Scoring Pasteboard or other Material, ofwhicli the following is a specification.

Thisinvention relates to machines for cutting and scoring pasteboard in the manufacture of paper boxes or other similar materials, especially that class of machines wherein the material is fed to revolving knives co operating with a revolving cylinder; and it consists, among other things, in the means employed for prod ucingthe required contact between the knives and the cylinder, as hereinafter fully set forth.

This invention is illustrated in the accompanying drawings, in which Figure l repre sents a side view, partly in section; Fig. 2, a vertical longitudinal section; Fig. 3, a plan or top view; Fig. 4, a detail view of the feed-rollers; Fig. 5, a like view ofthe cam; Fig. 6, a like view of the cutter-stock. Fig. 7 shows a modification ofthe tappets; Fig.8, a detached view of a modification showing a cutter-stock attached directly to a tappet; Fig. 0, a detached view of the cam and stop 8'.

Similar letters indicate corresponding parts. The letter A designates the machine-frame, supporting a table, B, next to the inner end of which are located feed-rollers C O, for presenting the material to be out and. scored to the knives or cutters D, between them and the cylinder E. These feed-rollers constitute means whereby the pasteboard or; other material, whetherinstrips or sheets, is continuously fed in an uninterrupted manner intothe machine and is continuously acted on by the automatically-reciprocated cutters, the latter acting to cut and seorethe material Whileitis fed forward in the manner stated. ThecylinderE revolves in fixed bearings situated on opposite sides of the machineframe, and its shaft is geared with a counter-shaft, F, as by cog-wheelsG, for receiving a revolvingmotion therefrom, and also gearedwith the lower feed-roller, O, as by abelt, H,Fig.3,fortransmittingmotion toit. Thecutters D have a circular shape, and are respectively connected to a stock or holder, I, by an axial pivot, I), so that they are capable of a revolving motion. The cutterstocks I are arranged opposite to the surface of the cylinder E, in brackets J, in a suitable manner to slide toward and from the cylinder, and a reciprocating motion is imparted thereto by the combined action of tappets K and springs L, the tappets being fixed to a rock-shaft, N, and

serving to move the stocks inward toward the cylinder, while thesprings are coiled'on the stocks and serve to move them outward. The tappets K are fixed to the rock-shaftN, respectively, by a set-screw, d, in order to render the same adjustable thereon, and in practice they are so adjusted transversely to the shaft as to move the cutter-stocks I inward afi sufficient distance to bring the cutters in superficial contact with the cylinder E in the motions of the shaft, thus adapting the knives to the purpose of cutting. The set-screws d may be arranged to impinge directly against the rock-shaft N, as shown in Figs. 1, 2, and 3, or they may be arranged to impinge against a rib or featherkey applied to the shaft, as shown in Fig. 7, in which case two screws are used for each tappet.

The brackets J are secured to a cross-head, O, which in turn is secured to the machineframe parallel to the cylinder, the brackets being adjustable, and thus allowing the positions of' the cutters to be varied lengthwise to the cylinder. The rockshaft N is mounted in brackets I, secured to the cross-head Q, and the motion thereof is produced by a cam, Q, which acts on an arm, R, fixed to the rock-shaft, to impart to such arm a vibrating'fmotion. In

this example the cam Q is composed of a revolving wheel, which is mounted on the eoun-J ter-shaft F, and provided with lugs Q on its periphery, forming the acting points thereof,

these lugsbeing adjustable on the wheel and.

also adjustable as to their own lengths, as by being made in sections, each provided with an" If desired, howpositions of theeutter-stocks I the knives D In practice the regu- 4 are out. of contact with the cylinder E and at such a distance therefrom as tobe adapted to the purpose of scoring.

Above or exteriorot' the springs L on the cutter-stocks respectively is placed a nut, g, for regulating the tension of the springs and holding them in place; but the springs can also be connected directly to the stocks at one end, omitting the nut.

In applyingvmy machine to use a revolving motion is imparted to the counter-shaft F, and

'a similar motion being thence transmitted to the cylinder E, while a reciprocating motion is imparted to the cutterstocks l, the material fed to the machine is alternately cut and scored by the cutters l), acting thereon as it passes I over the cylinder, the intervals ot'space cutand scored respectively depending onthe length and arraugemt nt of the lugs Q. a

'In order to insure the uniformity of the cut and scored blanks, each should be fed to the machine in a given position of the-camQ; and

i to-accomplish this object I. use an automatic feeder, S, w hich is arranged on the table B, and receives a reciprocating motion in a direction transversely to the plane of the feed-rollers O U at regular intervals, so that if a blank is laid on the table in the path of the feederitis thereby presented to the feed-rollers. The feeder S receives the required motion from the counter-shaft F by means of eccentrics U,connected to the feeder by pitmen U; butit may also receive its motion from the shaft of the cylinder E, or from any other source and by other mechanism than the eccentrics. The feeder S is used chiefly when the machine is driven by steam or other power, as when the 1 machine is driven by hand I can use in lieu of the feeder astop, S, which is combined with the cam Q in such a manner as to allow an unobstructed forward motion thereof, but check the same at a given point in its reverse 1. movement,thusdctermining its starting-point.

The feed-rollers G O revolve in superficial contact with each other, and the shaft of the u pper roller, 0 revolves in bearin gs T T, which are slotted to allow an up-and-down movement of such roller, and that end of the shaft rest ing in the bearing T is left entirely free, while the end thereofresting in the bearing T, is subjected to the action of a spring, I, or, in lieu thereof, a weight having a tendency to depress the same together with the corresponding end of the upper roller.

If the blank to be cut and scored is of narrow width, and it is presented to the feed-rollers O 0 near that end thereof where the upper roller is acted on by the spring l or its substitute, as indicated in Fig. 4:, the spring acts as a yielding support or fulcrum and counteracts the weight of the upper roller in the direction ofits opposite or free end, and thus keeps the upper roller parallel to the lower one, so that one edge and feed it in a curvilinear planeinstead of a rectilinear one. ln this example the spring 1 bears on a journal-box fitted in the slot of the bearing T, and it is provided with a tension-adjusting screw, 0,- but the spring or the weight substituted therefor can also be arranged in other readily-devisable ways.

If desired, the tappets K may be arranged to move the cutter-stocks I in both directions, omitting the springs L, as by bit'urcat-ing the tappets and grooving the cutter-stocks to receive such tappets, as shown in Fig. 8, the groove being preferably formed by two nuts to allow. the adjustment of the cutter-stocks.

Theconnecting-rods U can be made adj ustable to allow the position of the feeder b to be varied on the table, and, if desired, the feeder may be used independently of the feed-rollers O C to feed the material directlyto the cuttercylinder. 7

It should be observed that an essential and important element in the structure of the machine hereinbefore described is that mechanism or means in the form of continuously-revolving rollers is provided for the purpose of feeding the pasteboard or other material continuously or uninterruptedly, so that the automatically-reciprocated cutter-stocks and cutters will operate continuously on the material and cut and score the same, which combination of devices is of the utmost importance in order to provide a machine where the cuts and scores will be uniform and accurately produced.

A machine for cutting and scoring pasteboard has heretofore been composed of stationary cutter-stocks, combined with a cylinder caused to move to and from the cutters at stated intervals; but such is not my invention. In my machine the cutter-stocks are connected with deviceswhich act to automatically move the cutter stocks and their cutters toward and from a cutter-cylinder which revolves in stationary bearings, whereby the cutters will out and score the pasteboard, while the cuttor-cylinder, rotating in stationary bearings,

will not affect or change the horizontal plane of movement of the pasteboard, thereby renderingthe machine very efficicnt and positively accurate in operation.

A machine for perforating paper has also been composed of circular rotating punches, combined with devices to automatically stop at intervals the feed of the paper to be perforated and lift the said circular perforators to permit the paper to be adjusted or manipulated. Neither is such my invention. In my machine I provide mechanism such as revolving feed-rollers, which are continuously rotated in order to feed the material to the automatically-reciprocated cutters in a continuous or uninterrupted manner, which combination is essential to provide an efticient machine for accurately and uniformly cutting and scoring pasteboard or other material.

What I claim as new, and desire to secure by Letters Patent, is-- 1. In a machine for cutting and scoring pasteboard and other materials, the combination of mechanism, such substantially as described, operating to continuously and uninterrnptedly feed the material forward, with a cutter cylinder revolving in stationary bearings and a cutter-stock automatically moved toward and from the cnttencylinder during the operation of the machine for successively cutting and scoringthematerialwithoutchangingtheplane of its movement between the cutter-cylinder and cutter, the said combination being and acting essentially as and for the purposes set forth.

2. In a machine for cutting and scoring pasteboard and other material, the combination of mechanism, such substantially as described, operating to continuously or uninterrnptedly feed the material forward, with a cutter-cylinder revolving in stationary bearings, a cutterstock arranged adjacent to the cutter-cylinder and carryingacntter, and mechanism, substantial] y such as set forth, connected with the cutter-stock and acting to automatically move the same toward and from the revolving cuttercylinder, whereby the pasteboard or other material can be successively cut and scored without changing its plane of movement between the cylinder and the cutter.

3. The combination of a contiuuouslyoperating feeding mechanism operating to feed the material uninterrnptedly, with a cutter-cylinder revolving in stationary bearings, a cutterstock arranged adjacent to the surface ofsaid cylinder and carrying a cutter, a rock shaft, and a tappet thereon acting on the cutter-stock for imparting motion thereto, substantially as and for the purposes described.

4. In amachineforcuttingandscoringpasteboard and other materials, the combination of mechanism, such substantially as described,operating to continuously and uninterrnptedly feed the material forward, with a cutter-cylinder revolving in fixed bearings, a cutter-stock carrying a cutter arranged adjacent to the surface of the cylinder, at rock-shaft, a tappet mounted on said rock-shaft and acting on the cutter-stock to move it in one direction, and a spring arranged to move the cutter-stock in the opposite direction, substantially as and for the purpose described.

5. In a maehinefor cutting and scoring pasteboard and other materials, the combination of mechanism, such substantially as described, operating to continuously and uninterrnptedly feed the material forward, with the cutter-cylinder revolving in fixed bearings, the cutterstock arranged adjacent to the surface of the cylinder, the rock-shalt, the tappet arranged on said rock-shaft and acting on the cutterstock to move it in one direction, a spring arranged to move the cutter-stock in the opposite direction, the vibrating arm fixed to the rock-shaft, and the cam for actuating the vibrating arm, substantially as described, for the purposes set forth.

6. In amachinefor cutting and scoring pasteboard and other materials, the combination of mechanism, such substantially as described, operating to continuously and uninterrnptedly feed the material forward, with a cutter-cylinder revolving in stationary bearings, a stationary cross-head above the same, a bracket arranged thereon, and a cutter-stock automatically moved upon said bracket toward and from the revolving cutter-cylinder to successively cut and score the pasteboard or other material supported by the said cylinder.

7. In a machine for cutting and scoring pasteboard and other materials, the combination of mechanism, such substantially as described, operating to continuously and uninterrnptedly feed the material forward, with a cnttercylinder revolving in stationary bearings, a stationary cross-head arranged above the same, a series of laterally-adjustable brackets arranged thereon, a series of cutter-stocks supported'on said brackets, and mechanism, substantially such as set forth, automatically moving the cutter-stocks on the said brackets toward and from the cutter-cylinder, for successively cutting and scoring the pasteboard or other material.
